Power Amplifiers

New microwave systems need a more sophisticated power management. The power amplifiers determine the overall system efficiency and thereby the operating costs.

At FBH, new amplifier designs are developed and existing ones are improved to fabricate integrated power amplifier circuits and modules. They are realized in GaN-HEMT technology and target applications in e. g. satellites, base stations and measurement equipment.

• Switch-mode amplifiers for class S systems (up to 2 GHz) and other switch-mode concepts (class E)
• Linear power amplifiers for X band (class A/AB)
• Concepts for envelope elimination and restoration (EER)
• Broadband amplifiers and power traveling wave amplifier concepts
• Multi-band power amplifiers

• Digital switch-mode amplifiers for application in class-S systems at 1.8 Gbit/s with 8 W output power and 90% efficiency (broadband signal)
• Power amplifier 9,5 GHz to 10,5 GHz with 15 dB gain, 10 W output power and 33 % efficiency
• Class E amplifiers at 2 GHz with 4 W output power and 62% efficiency
• Broadband power amplifiers between 0 and 10 GHz with 4 W output power
